Results

After a successful calculation, the results of the modal analysis load case are displayed: You can see the first mode shape in the work window; the eigenvalues and natural frequencies of the individual mode shapes are in the table. The dynamic analysis results are thus fully integrated into the program interface of RFEM or RSTAB.

Results of Modal Analysis in Work Window and Table

Work Window

Select a mode shape whose results should be graphically displayed from the list at the top of the "Navigator – Results". You can also use the buttons and to switch between the individual mode shapes.

Selecting Mode Shape

The following result types are available for the graphic display in the Navigator:

• Mode Shape: absolute total displacement; normalized displacement in u_X, u_Y, or u_Z; normalized rotation in φ_X, φ_Y, or φ_Z
• Masses: translational components of the displacements u_X, u_Y, or u_Z; rotational components of the rotations φ_X, φ_Y, or φ_Z
• Values on Surfaces

Table

The result tables of the dynamic analysis are displayed automatically when displaying the results of a dynamic load case. You can use the categories and subcategories to control the display of the results in the table (see the chapter Tables of the RFEM Manual). Various subcategories are available for the modal analysis, which are presented in the following chapters.
